SIFTER.

SPECIFICATION forming part of Letters Patent No. 291,576, dated January S, 1884.

Application filed March 22, 1883. (No model.)

To aZZ whom it may concern:

Be it known that I, HERBERT CLAYTON, of Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Sitters; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilledin the art to which it pertains to make and use it, reference being had to the accompanying drawings, which form part of this specification.

My invention relates to improvements in sifters; and it consists in the combination of the sifter-frame, which has its two ends pivoted together at their upper edges, and which are adapt-ed to open outward at their lower edges, a latch for holding the frame closed, a removable sieve, crank-shaft, and the revolving frame, which forces the substances being sifted through the sieve, and a pin for locking the revolving frame to the shaft, as will be more fully described hereinafter.

The object of my invention is to provide a sifter in which the sieve is made readily removable, either for the purpose of cleaning it or for the purpose of replacing it by another, and in which the revolving frame can be readily detached from the crankshaft for the purpose of enabling it to be cleaned.

Figure 1 is a side elevation of the sifterframe, showing it open for the removal of the sieve. Fig. 2 is avertical cross-section. Fig. 3 is a detail view of the revolving frame.

A represents the sifter-frame, which is preferably made of a tubular shape, andfprovided with a handle, B, in the usual manner. The

ends of this frame A are pivoted together at 0, while the lower edges of these ends have no othermeans of connection than the wire 0, which projects from one side and passes into a suitable socket, b, which is formed upon the opposite one. By connecting these ends together at their upper edges and allowing the lower edges to be drawn apart, the frame can be opened, as shown in Fig. 1, for the purpose of allowing the sieve F to be readily removed. The wire 0 is fastened in the lower edge of the frame A, for the purthe sieve has been used and it is desired to pose of strengthening it, and one end is allowed to project, as shown, for the purpose of forming a guide and bringing the edges together.

In the frame, at any suitable point, there is formed a groove, H, in which the upper edge of the sieve F is made to catch. As long as the frame is closed, as shown in Fig. 2, this sieve will be held securely in place; but when the lower portion of the frame A is open, as shown in Fig. 1, the sieve can be readily removecb For the purpose of holding the two ends of the frame tightly together, the notched latch G is provided. By thus making the sieve removable, sieves of different grades can be used in the same frame, and the sieves can be removed and replaced with but little trouble when it is desired to clean them.

The revolving frame J, which is secured to the crank-shaft L, is locked to the shaft by means of the pin or wire I, which passes down through one of the ends of the revolving frame J and through the crank-shaft. After remove the frame and the crank-shaft for the purpose of washing them thoroughly, it is only necessary to pull out the pin, and then volving frame removed.

Pin 1 is made from a single piece of wire, which is bent near its center into one-or more coils, so as to form a spring, and which has a hook formed on one of its ends. This pin forms a locking device which cannot become accidentally displaced as the frame is being revolved.

It will readily be seen that the crank-shaft L extends through one end of the frame J. and thus it is only necessary to provide the frame with a pivot, (1, upon the opposite side or end. By this construction the long rod which usually passes through the center of the frame is entirely dispensed with.

Having thus described my invention, I claim- 1. A sift-er-fra1ne which has its ends piv- '5 oted together near their upper edges, and which the crank-shaft can be drawn out and the re I eons-7o is provided with the guiding-wire G and the socket b at its'lower edges, and a pivoted described.

locking-latch, G, in combination with the In testimonywhereof I affix my signature in sieve F and revolving frame J substantially presence of two witnesses.

' 5 as shown. HERBERT CLAYTON.

2. A revolving frame, J, provided with the pivot d, the short crank L, and a spring locking-pin, I, in combination with the frame A and sieve F substantial] as shown and 7 y I Witnesses:
